如何在程序持续运行的同时停止带有pygame的函数

import pygame
pygame.init()

running = True

while running:
    # 执行pygame函数的代码
    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

running = False

import pygame
pygame.init()

def my_function():
    # 带有pygame的函数代码

running = True

while running:
    # 执行pygame函数的代码
    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

# 停止带有pygame的函数
running = False
